I`m looking for the official, factory, dimensions for this shorter masted version of the cal 34 called the san Francisco rig. I`m ordering a mainsail and would like to provide stock measurements from factory specs.
thanks, bill

Bill, I can't supply the stock dimensions, but would strongly suggest that you not trust them when ordering a mainsail for a boat that old. In thirty odd years, previous owners can make the most astonishing alterations in things, and even respected builders like Cal sometimes make changes as the model matures.

All legitimate sailmakers will come to your boat and make the needed measurements in situ. To do otherwise begs for an ill-fitting mainsail.
